Original a pnc iimi filed February :21 1 919,.Serial No. 278,392. Divided and this application filed Ia nary 3 1920.- Seria1 -No.349,206.

T all 11']: (mi it may con't'cmif lie it known that I, Dnauc'rnizos J .Dnaias, ,acitizen of the .I.n1ted States, residing at Pittsburgh, in the. county of Allegheny and State of Penns \"lvan1a, have invented cer- I tain newv and useful Improvements in Fask tening Means for T ire-Cl' alns, of which the following. isa specification.-

This invention relates to.fasteningmeans .for tire chains, audit comprises a bolt or lug projectingfromthcflfelly of the wheel at each side, in con' bination with a chain. adapted to be arranged transversely of the tire. said chaln being provided w1thU- shaped fastening, elements at. each end, a fastening devlce secured to each of saldelements, and held in place by said bolts, and

a securing plate arranged over said fasten- 111g device-and held in place'by sald bolt,

said securingplate being provided with recesses for the reception of said fastening de-, v ce, all as more fully. herelnafter set forth and as claimed. 1 v

This application is. a division of my copending application for improvements in resilient tires filed February 21st,. 1919,

- Serial No. 278,392, which has since become PatentNo. 1,337,443, dated April 20,1920. In the present invention I have devised simple and efiicient means tor-securely fas tening nonskid chains to'tires.

'- plied .when needed andfcan easily be reof Fig. 1;

moved when desired. i

In the --.accompanying drawings I have shown several embodiments of this invention. 7 In the showing Figure 1 is a side elevation-of a wheel with a tire applied thereto showing one form of the invention. a

Fig; 2 is a sectional view taken on-the .line' 2- 2 of Fig-"1., i 1 a Fig. .3 is ase ctional view on the line 33 V The device, 15 of simple construct on, can be readily ap- Fig. 9, is a transverse sectional view .on

the line 51-Oct Fig. 8, and

Fig. 1 0'is a side elevation ofthe securing V trated as applied to the solid cushion tire.

In Fig. of the drawings thetire is of a pneumatic type. The wheel is provided with felly (see Figs. 2 and 3) and a nonskid chain 4 is arranged over the tread of the tire and received in recesses 5 in the tread portion. The particular type of tire herein illustrated and the particular type of nonskid chain form no part of the present invention, being claimed in my copending application. It will be apparent that the securing means herein claimed may be employed in connection with nonskid chains on any type of tire, and may be employed in connection with any form of nonskid chain.

shown, the chain consists of two substantially parallel sections provided with U- shaped elements 6 at each side. The fastening device 7 is provided with a hooked end 8 adapted to be received in the U-shaped section. The op osite end of the fastening device is provi ed with an eye 9 for the re ception of a threaded lug or bolt 10 project-' ing. from the side of the felly. The secur ing plate 11 is arranged over the fastenin device and this securing plate is provided with a longitudinal recess 12 (see Fig. 10) for. the reception of the fastening device.

. The securing plate is provided with anaperture 13 for the reception of the bolt and acircular depression or groove 14.1s arranged nearthis aperture for the reception of the eye 9 formed on the end of the fastemng device. Nuts 15 are adapted to be placed on the threaded lugs, and it will be apparentwhen the nuts are tightened the nonskid chain will be securely held in position.

Referring to Figs. 6 and '7 of the drawings, as herein shown the longitudinal recesses in the securing plate are omitted. As shown the securing plate is secured to the wheel by bolts 10 and nuts 15. The inner side of the securing plate is providedwith a shoulder 16 adaptedto coact' with the flange 17 formed on the rim 18 on the wheel. The securing device 7 is received in a longitudinal groove 19 extending from the upper edge of the securing plate to the shoulder 16. The securing device is provided with a horizontal offset portion 20 which is received beneath the flange of the rim for holding it in position.

As shown in Figs. 8 and 9 of the drawing the securing device comprises a loop 21. This loop passes through the U-shaped portion 6 arranged on the end of the chain and is received between the securing plate 11 and the telly 3. As shown, itis provided with offsets 22 and QBsh-aped to fit beneath the rim and the flange formed on the rim for securing it in position. is received in grooves or recesses 24 and 25 formed in the securing plate. I

The operation of this device will be readmy apparent to one skilled in the artv and further "description thereof is deemed unnecessary. -It is obvious that the means herein described and illustrated produces a very eflicient construction for fastening antiskid chains to vehicle tires, and with that the device may be readily applied or removed.

As stated, the device is susce tible of use in connection with any type 0 tire, either pneumatic, solid, or cushioned, and may be employed with any t pe' of chain. It will be apparent that the evice can be employed in connection with .a tire chain consisting of a plurality of elements joinedtogether and extending entirely around the circumference of the tire. When employed with this type of chain it is merely necessary to provide fastening means at intervals upon each side of the chain.

It is understood that'the above disclosure merely illustrates certain advantageous embodiments of the invention and that various changes may be made in thedetail construction and arrangement of arts without departing from the spirit oi the invention or the scope of'the subjoined claims.

What I claim is: I g

1. A fastening device for antiskid chains for tires, comprising threaded projections carried by thefelly of the wheel, fastening devices secured to the end of said chain, securing plates arranged on saidprojecti'ons, said securing plates being provided with recesses for the reception of the fastening elements and means for securing said plates on the threaded project-ions. Q

2. In combination with a wheel and a tire mounted thereon, anti-skid chains arranged transversely of said tire, and fastenthe wheel, an eye ing means for said chains,.said means comprising threaded projections carried by the to the end of the chain, the securing plate being provided with recesses on the inner side, said. fastening device being adapted .to be positioned in said recesses.

3. In combination with a wheel and a tire mounted thereon, anti-skid chains arranged transversely of said tire, and fastening means for said chains, said means comprising threaded projections carried by the wheel, asecuring plate mounted on each. of said threaded projections, and a fastening device, said fastening device being secured to the end cram chain, and extending between said securingplate and thefelly of the wheel, the securing plate being provided.

with recesses for the receptionof said fastenine' device.

4. in combination with a wheel and a tire mounted thereon, anti-skid chains arranged transversely of said tire, and"fastening means for said chains, said means comprising threadedfprojections carried by the I wheel, a securing plate mounted oneach of said threaded .pro ect1ons, and a fastening device, said fastening device being secured to the end ofthe chain, and extendin' be tween said securing. plate and the fel of thewheel, an eye formed on the end 0 the fastening device and adapted to be received by saidthreaded lug, the securing plate being provided with recesses for the reception of said fastening. device.

' 5. In combination with a wheel and a tire mounted thereon, anti-skid chains arranged transversely of said tire, and fastening means for said chains, said means comprisin-g threaded projections carried by the wheel, a securing plate mounted on'each of said threaded projections,'and a fastening device, said fastening device being secured to theend .of the chain, and extendin between said securin plate and the fel v of farmed on the end of the fastening device and adapted to be received by said threaded lug, the securing plate being provided with recesses for the reception of said fastening device, and an annular depression .in said securing plate for the reception of the end of said -fastening device. n testimony whereof I afiix my signature in presence of two witnesses.
